Temporary Aortic Occlusion Device

Abstract

Blood vessel occlusion devices, systems and methods, in particular embodiments of devices for aortic occlusion. The device includes one or more locator portions and an occluder portion. The device is delivered via transcatheter delivery. The locator portion may be radially expanded using a handle and actuator at the proximal end of the delivery catheter. Tactile feedback from the locator portion is used to determine proper location of the occluder portion, for example within the abdominal aorta. The occluder is then radially expanded to occlude the vessel.

AI Technical Summary

Benefits of technology

[0015]The present invention is directed to a temporary aortic occlusion device having an expandable locator portion and an expandable occlusion portion. The expandable locator portion assists a user in determining whether the distal end of the device has been advanced within a patient's aorta, and the occlusion portion is expanded to occlude the patient's aorta, preferably below the renal arteries.

[0016]In one embodiment, the locator portion has a maximum expansion diameter that is smaller than a maximum expansion diameter of the occlusion portion. Additionally, the locator portion preferably has a maximum expansion diameter that is the same size or slightly smaller than the internal diameter of a patient's aorta, providing the user with little or no resistance to expansion when positioned in an aorta.

Problems solved by technology

Existing solutions for blood vessel occlusion have various drawbacks, including surgical invasiveness and requirements for complex imaging and guidance of the device.
